Percona XtraBackup 2.2.1 alpha release is now available

Percona is glad to announce the release of Percona XtraBackup 2.2.1-alpha1 on March 28th 2014. Downloads are available from our download site here. This ALPHA release, will be available in our Debianexperimental and CentOStesting repositories.

This is an ALPHA quality release and it is not intended for production. If you want a high quality, Generally Available release, the current Stable version should be used (Percona XtraBackup 2.1.8 in the 2.1 series at the time of writing).

This release contains all of the features and bug fixes in Percona XtraBackup2.1.8, plus the following:

New Features:

Percona XtraBackup has removed the multiple binaries (xtrabackup_56, xtrabackup_55, xtrabackup) and now uses single xtrabackup binary instead for handling backups. Single binary implementation removed the requirement to download server source tarballs and removed different patches which resulted in cleaner code.

Percona XtraBackup source layout has been changed to implement the single binary. Percona XtraBackup code can now be found in storage/innobase/xtrabackup.

Percona XtraBackup can now store backup history on the server itself in a special table created for that purpose.

innobackupex-1.5.1 symlink has been removed, instead innobackupex binary should be used.

Percona XtraBackup has removed the build.sh script and it’s now built with CMake.

Percona XtraBackup has been rebased on MySQL 5.6.16.

Bugs Fixed:

Information about tool version used to take the backup was added by implementing backup history feature. Bug fixed #1133017.

If an XtraDB-based binary was used to a backup an InnoDB database, it would convert it to XtraDB by adding the XTRADB_1 marker in the dictionary header page and by adding the SYS_STATS table. Bug fixed #988310.
